Near the front of the intake manifold, you will see the EGR valve. Disconnect the electrical connector, remove the two 10 mm head bolts, remove the lead coated gasket from the intake. Be sure to clean the surface of all evidence of the gasket, using care to not get any into the intake. Place the new gasket on the EGR valve, using the bolts to keep it in place, put the new EGR on the intake. Tighten the bolts up evenly, plug the connector back in, and Rock and Roll.
It is right beside of the thermostat housing, right side of it. Just follow the top radistor hose to the engine and it will clamp to the thermostat housing.

That year truck does not have a modulator valve on the transmission. it has a electronic transmission in it.
It is in the top of the valve cover. It has a black plastic line coming from the throttle body housing and going into one of the valve covers. It will be stuck in the end of the line and down into the valve cover.
